SOAP-WS Authorization Problem with SoapUI 5.4.0

Hi!

I've a strange problem in SoapUI 5.4.0 with authorization for a SOAP webservice. I need to be authenticated with Basic-Auth to ask my service.

When I send my username/password with Basic-Auth, it works, I've the correct answer from the service.

But then, I change the authorization method and set "No Authorization". I run the request again, and get the same answer from the service. If I check the raw-request, there is "Authorization: Basic c2EtVGF4aXN...", same as with Basic-auth! Same if I delete the Basic-auth configuration before running the request.

Is this a bug of the version 5.4.0, or am I doing something false?

Thanks for the answers
